Costanzo, Joseph, Cynthia J. Davis, Caribert Irazi, Daniel M. Goodkind, and Roberto R. Ramirez.  "Evaluating Components of International Migration: The Residual Foreign Born."   January 2002.  50 pages.
Abstract:  On March 1, 2001, the U.S. Census Bureau issued the recommendation of the Executive Steering Committee for A.C.E. Policy (ESCAP) that the Census 2000 Redistricting Data not be adjusted based on the Accuracy and Coverage Evaluation (A.C.E.). By mid-October 2001, the Census Bureau had to recommend whether Census 2000 data should be adjusted for future uses, such as the census long form data products, post-censal population estimates, and demographic survey controls. In order to inform that decision, the ESCAP requested that further research be conducted.

Between March and September 2001, the Demographic Analysis-Population Estimates (DAPE) research project addressed the discrepancy between the demographic analysis data and the A.C.E. adjusted estimates of the population. Specifically, the research examined the historical levels of the components of population change to address the possibility that the 1990 Demographic Analysis understated the national population and assessed whether demographic analysis had not captured the full population growth between 1990 and 2000. Assumptions regarding the components of international migration (specifically, emigration, temporary migration, legal migration, and unauthorized migration) contain the largest uncertainty in the demographic analysis estimates. Therefore, evaluating the components of international migration was a critical activity in the DAPE project.

This report focuses on the evaluation of the U.S. Census Bureau’s estimated residual foreign-born population (including both unauthorized and quasi-legal migrants) in 1990 and 2000.  The estimates shown here were calculated in conjunction with estimates of other components of international migration: legal permanent migration and legal temporary migration. These components of international migration, along with assumed deaths and emigrants, are subtracted from a total foreign-born population yielding a residual count. Most of this residual foreign-born population is assumed to be the unauthorized migrant population. However, included in this residual number are some quasi-legal migrants present in the U.S.

According to our calculations, the estimated residual foreign-born population in 1990 was 3,765,906 and 8,705,419 in 2000. In 1990, the residual foreign born were less likely to be male (48.4 percent) than in 2000 (54.2 percent). Of the residual foreign born, 26.8 percent were from Mexico in 1990 and 44.5 percent were from Mexico in 2000.

Future research will focus on decrementing the 1980 and 1990 unauthorized populations for known legal migrants, using final Census 2000 sample data, exploring alternative data sources and alternative assumptions and methods. Future research will support the production of annual estimates of unauthorized migrants.

Cassidy, Rachel and Lucinda Pearson.  "Evaluating Components of International Migration: Temporary (Legal) Migrants."  No. 60.  January 2002.  23 pages.
Abstract:  On March 1, 2001, the U.S. Census Bureau issued the recommendation of the Executive Steering Committee for A.C.E. Policy (ESCAP) that the Census 2000 Redistricting Data not be adjusted based on the Accuracy and Coverage Evaluation (A.C.E.).

Assumptions regarding the components of international migration (specifically, emigration, temporary migration, legal migration, and unauthorized migration) contain the largest uncertainty in the demographic analysis estimates. Therefore, evaluating the components of international migration was a critical activity in the DAPE project.

This report focuses on the evaluation of the U.S. Census Bureau’s estimated stock of legal temporary migrants in 1990 and 2000. Specifically, the review process validated the estimates of temporary migrants in 1990 and created an intermediate estimate for 2000. To produce the estimate of net temporary migrants, the Census Bureau developed criteria, related to visa requirements, to identify people who were likely to be resident temporary migrants in the 1990 census. Because the preliminary data from Census 2000 were unavailable for several necessary variables for the algorithm (e.g., industry and income), data from the Census 2000 Supplementary Survey were used for the 2000 estimate.

Our evaluation resulted in a temporary migrant stock estimate of 487,453 in 1990 and 781,507 in 2000. For both dates, temporary migrants included more men than women, were likely to be non-Hispanic, and the largest numbers were between the ages of 18 and 29. Future research will focus on an evaluation of the criteria used for the algorithm, and an adaptation of the algorithm to other surveys, such as the Current Population Survey and the American Community Survey, to facilitate in the production of annual estimates of temporary migrants.

This report focuses on the evaluation of the U.S. Census Bureau's estimates of the foreign-born population by migrant status in 2000. In particular, we assess the assumptions used to estimate the various types of international migrants (legal immigrants, temporary migrants, unauthorized migrants, and emigrants) and the effect of alternative assumptions in estimating the size of the foreign-born population. By reviewing alternative assumptions about the types of international migrants, we assess the completeness of coverage of the foreign-born population in Census 2000, and the reasonableness of the resulting Demographic Analysis (DA) estimates.

Bishai, David.  "Does the Law of Diminishing Returns Apply to Infant Mortaility Decline?"  WP 01-03.  September 2001.  16 pages.
Abstract:  
Objective: This paper examines time series data on infant mortality from 21 countries to demonstrate an appropriate test of the hypothesis that percentage reductions in infant mortality are larger when infant mortality is lower. Prior research expounding this hypothesis has dubbed it "the Matthew effect". Method: Time series for infant mortality can be modeled as X t = m + q1 X t-1 +e t where e t is identically and independently distributed. If q1=1 it is easily demonstrated that the time series has an asymptotic distribution with infinite variance. The correct test to apply in this situation is the Dickey-Fuller test which we use to test the statistical significance of q1 in a regression analysis of Dlog IMR t = m + q1 log IMR t-1 +e t. Evidence that q1 is significant and negative would support the claim that there is a Matthew Effect in infant mortality. This paper uses time series data on IMR from 21 nations for 1870-1988. Several additional lagged values of Dlog IMR were appended using an Akaike Indicator Criterion to select the preferred specification. Transformations of IMR other than simple logarithms were explored.

Results: With the preferred specification, the Dickey-Fuller test rejected the presence of any Matthew Effect in all but three countries. The rejection of a Matthew Effect was robust to alternative specifications of the lag structure of IMR and to various transformations of IMR other than logarithmic.

Conclusion: Based on 20th century data there is scarce evidence that percentage reductions in infant mortality are generally smaller in higher mortality countries. Large percentage reductions in infant mortality are possible for countries at any stage in economic development and are likely to be reflective of durable advances in human knowledge, social institutions, and physical capital.

Hill, Kenneth.  "Methods for Measuring Adult Mortaility in Developing Countries:  A Comparative Review."  WP 01-02.  August 2001.  24 pages.
Abstract:  No consensus has emerged on how to estimate adult mortality in countries lacking complete vital registration of deaths and accurate periodic censuses. This paper applies a range of methods to census, registration and survey data for Guatemala for the period from 1981 to 1994. The findings are less than conclusive because of marked errors in the census populations. Methods using intercensal survival perform very poorly, giving rise to results that are hard to interpret. Methods using the distribution of deaths by age and rates of change of the population by age appear to work better, but still give rise to substantially different results. Simulations suggest that a combination of two methods appears to work well. In the Guatemala case, survival of mother appears to over-estimate female adult mortality, whereas survival of siblings appears to underestimate adult mortality. A new method for analyzing intercensal changes in cohort proportions with surviving mother, presented in the paper, gives results broadly consistent with estimates based on adjusted registered deaths.

Hill, Kenneth, George Bicego, and Mary Mahy.  "Childhood Mortality in Kenya:  An Examination of Trends and Determinants in the Late 1980's to the mid 1990's."  WP 01-01.  August 2001.  16 pages.
Abstract:  After Independence in the early 1960s, child mortality in Kenya fell rapidly. Until around 1980, the under 5 mortality rate (U5MR), the probability of dying by age 5, fell at an annual rate of about 4 percent per annum. This rate of decline slowed in the early 1980s, to about 2 per cent per annum. Recent data from the 1998 Kenya Demographic and Health Survey showed that, far from declining, the U5MR increased by as much as 25 percent from the late 1980s to the mid 1990s. This adverse trend coincided with a number of other adverse trends: stagnation in growth of per capita income, declining levels of immunization, falling school enrolment, and the emergence of an HIV/AIDS epidemic. On a more positive note, fertility fell by about 30 percent from the mid 1980s to the mid 1990s. Controversy surrounds the factors responsible for the increase in child mortality in the 1990s, and the objective of this paper is to clarify the situation. Data from the 1993 and 1998 DHSs have been merged into a single data set, and multivariate analysis used to examine the factors associated with mortality risks in childhood. Dummy variables were used to represent different three-year time periods, from 1984-86 to 1996-98. Socioeconomic controls, including mother¹s education, an indicator of household wealth, urban/rural residence, and indicators of health service utilization, plus controls for reproductive dynamics such as age of mother at the birth, birth order, sex and preceding birth interval, were developed. In addition, an indicator of the HIV epidemic, the prevalence of HIV in the district of birth at the time of each child¹s birth, was developed. With no controls, the models confirmed an increase in mortality of about 25 percent. Including socioeconomic and biodemographic controls tended to strengthen the upward trend in mortality; in other words, had there been no changes in these factors, child mortality would have been expected to decline. Introducing controls for health variables ­ immunization, pregnancy and delivery care, prevalence of childhood diseases and maternal and child malnutrition ­ also did not alter the underlying trends substantially. Thus rising child mortality could not be explained by socioeconomic, biodemographic or health status factors. Including the prevalence of HIV in the models, however, changed the underlying trends fundamentally, from sharp increase to monotonic decline. Although models of this sort cannot demonstrate causation, only association, the HIV epidemic appears to be the most probable cause of the recent increases in child mortality in Kenya. Of the health variables, the only one found to be significantly protective was immunization coverage.

Christopher, Karen.  "Caregiving, Welfare States and Mothers' Poverty."  No. 287.   November 2001.  38 pages.
Abstract:  I begin with a review of the literature that considers the gendered assumptions upon which many welfare states base their social policies. Next I present my research questions, discuss data and methods, and present analyses of how welfare states affect the poverty rates of mothers, single mothers, and other citizens in nine Western nations (Australia, Canada, Finland, France, Germany, the Netherlands, Sweden, UK, and US). The analyses show the extent to which social assistance programs reduce mothers' and single mothers' poverty rates-in an absolute sense, and also how welfare states reduce their poverty rates relative to the poverty rates of other roups (such as female non-mothers or non-single mothers). I find that the welfare states most representative of the "male breadwinner" model (Germany and the Netherlands) are problematic not only with their gendered assumptions about women's carework; compared to other countries, they also do less to reduce mothers' poverty rates relative to those of female non-mothers and men. In other words, in Germany and the Netherlands, many social policies assume that mothers are primary caregivers, but their social assistance programs fail to lower mothers' poverty rates relative to those of other citizens. I conclude with the implications of these findings for mothers' economic dependence on male partners. First, I present a brief discussion of the theoretical literature on the gendered nature of welfare states.

Christopher, Karen. "Welfare State Regimes and Mother's Poverty."  No. 286.  November 2001.  45 pages.
Abstract:  In this paper I assess the extent to which welfare states reduce poverty among single mothers and all mothers. I focus on two different typologies of welfare states. One identifies the gendered assumptions underlying social policies, while the other focuses
on how welfare states and labor markets affect class inequality. Using data from the Luxembourg Income Study, I show how tax and transfer systems and employment supports in nine Western nations affect the poverty rates of single mothers and all mothers vis-à-vis other groups. I find that particularly in the Scandinavian nations, and to a lesser extent in France, the Netherlands and U.K., the tax and transfer system, employment supports, or a combination of the two allow most single mothers to form autonomous households that escape poverty. I conclude by discussing how my findings speak to the different typologies of welfare state regimes.

Christopher, Karen.  "Single Motherhood, Employment, or Social Assistance:  Why are U.S. Women Poorer than Women in Other Affluent Nations?"  No. 285.  November 2001.  29 pages.  
Abstract:  U.S. women have higher poverty rates than women in other affluent nations. In this paper I attempt to explain this disparity by examining the effect of single motherhood, employment, and social assistance on women's poverty. With cross-national comparisons of quantitative data, I find that the relatively high rate of single motherhood among U.S. women is not a main cause of their high poverty rates. Compared to their counterparts in other Western nations, U.S. women, mothers and single mothers are among the most likely to earn poverty wages. In addition, U.S. social assistance programs are the least effective in reducing poverty. I conclude with the policy implications of my findings, focusing on strategies to ameliorate the high poverty rates of U.S. women and mothers.

Fernández, Raquel, Nezih Guner, and John Knowles.  "Love and Money : a Theoretical and Empirical Analysis of Household Sorting and Inequality."  No. 283.  September 2001.  54 pages.
Abstract:  This paper examines the interactions between household matching, inequality, and per capita income. We develop a model in which agents decide whether to become skilled or unskilled, form households, consume and have children. We show that the equilibrium sorting of spouses by skill type (their correlation in education) is increasing as a function of the skill premium. In the absence of perfect capital markets, the economy can converge to dierent steady states, depending upon initial conditions. The degree of marital sorting, wage inequality, and fertility dierentials are positively correlated across steady states and negatively correlated with per capita income. We use household surveys from 34 countries to construct several measures of the skill premium and of the degree of correlation of spouses' education (marital sorting). For all our measures, we find a positive and significant relationship between the two variables.

Hakovirta, Mia.  "The Income Sources of Single Parents: a Comparative Analysis."  No. 282.  November 2001.  35 pages.   
Abstract:  The aim of this article is to examine the different income sources of single parents using the method of the income packages. The concept of income package highlights the importance of both the source and the level of income of single parent families in different welfare states. These potential sources of income are central when analysing the nature of support offered by the welfare state to single parents. This article attempts to give answer to the following questions: 1. Is it the case that the degree to which single parents participate in paid employment influences their income packages? In those countries where paid employment is common among single parents, is the main component of their income packages income from work? In contrast, in those countries where paid employment is rare among single parents, are incomes mainly derived from social transfers? 2. How has the income sources of single parents changed during the economic downturn in some countries during the 1990s? Has the dependency on state benefits increased and the amount of income from employment decreased as a result of a weakened labour market position among single parents? The study focuses on the turn of the decade (namely 1983-86 and 1991-95) when social policy was reformed in many countries. The countries selected for this study are Australia, Britain, the US, the Netherlands, Germany, Norway, Finland and Denmark. The article starts with an overview of the different work requirements of single parents across countries. This serves as a platform for empirical analysis on income packages. Then the changes in labour market participation rates of single parents are studied. This is followed by a study of the income packages and income levels of single parents. The article concludes with a discussion of the main research findings.

Billari, F.C. and C. Wilson.  "Convergence towards diversity?  Cohort dynamics in the transition to adulthood in contemporary Western Europe."  2001-39.  December 2001.  30 pages. 
Abstract:  This paper addresses the transition to adulthood in developed countries. It reviews the main theories that have been employed in recent years to explain trends in such variables as age ages at leaving home, union formation, first marriage and first birth. The paper then examines the median ages at which women in nine European countries experienced these events and the inter-quartile range within each cohort. The results do not provide unequivocal support for any of the main theories. In conclusion we offer some speculative remarks on what form an alternative theory might take.

Abstract:  We use three waves of the European Community Household Panel (ECHP) to analyse the impact of employment, earnings, household income, and welfare on young adults’ decision to leave the parental home. In particular we investigate the importance of these income sources in different welfare settings. We use a simultaneous equation approach to control for unobserved heterogeneity. This is important given that the ECHP does not include retrospective information on demographic events. We find employment and income to be very important factors in the decisions of young adults in the Southern European Welfare State to leave home. For the Continental European Welfare state the results are more mixed. Employment and income are still important factors, but the effects are less clear and there are significant variations. In the Scandinavian Social Democratic Welfare State, the effect of employment and income appears negligible. The effect is also modest in the UK (the Liberal Market State), a finding we attribute to the educational system.

Abstract:  We explore the strong linkages between macro changes and the dynamics of educational, occupational, family, and residential careers of young Spanish adults born between 1945 and 1974. We review theory and evidence on macro factors: changes in the welfare system, centrality of the family as a service provider, and the changing role of women. We outline some hypotheses of how life course trajectories, and their heterogeneity, change across cohorts. We build data on sequences of states using FFS. In our analysis, we find an increase in the discontinuity of careers and of the heterogeneity among cohort members, especially for employment. Women's careers are becoming more similar to those of men. Family and household formation is postponed, with a limited spread of post-nuclear family forms.

Abstract:  In this paper we investigate (1) the mutual causal relationship between first union formation and first childbirth, and (2) the existence of constant common determinants of these two events. It is argued that (unmeasured) common factors reflect differentials among the population in value orientations and in norms about the sequencing of events. We apply event history techniques to retrospective survey data for Spain, allowing for the correlation between unobserved heterogeneity components belonging to each process. Our findings confirm the strong interrelationship between union formation and first birth. After controlling for these common factors, we find that the risk of conception increases immediately at marriage, and it continues to be high during the following four years. Entry into cohabitation produces much smaller increases in the relative risk. The effect of the conception of the first child on union formation is especially strong during pregnancy, but declines sharply after delivery.

Boersch-Supan, Axel.  "Labor Market Effects of Population Aging."  #8640.  December 2001.  40 pages.
Abstract:  This paper analyzes effects of population aging on the labor market and determines their broad implications for public policy. It takes Germany as an example, but it equally applies to the other large economies in Continental Europe. The paper argues that, alongside the amply discussed, demographically-determined increase in the contribution and tax burden which is responsible for the ever widening gap between gross and disposable earnings, two other important areas of policy deserve greater attention. First, it is unlikely that the decline in the relative size of the economically active population will be offset by higher capital intensity. Labor productivity will need to increase over and above this mechanism in order to compensate for the impact of population aging on domestic production. Hence, we will need more education and training to speed up human capital formation. Second, the shift in the age structure will also change the structure of demand for goods. This, in turn, will have large effects on the pattern of employment across different sectors of the economy and will require a substantial increase in labor mobility in order to accommodate these structural changes.

Lichtenberg, Frank R.  "The Effect of New Drigs on Mortaility from Rare Diseases and HIV."  #8677.  December 2001.  27 pages.
Abstract:  I investigate the effect of large increases in the number of drugs available to treat rare diseases and HIV on mortality associated with them. Mortality from both diseases declined dramatically following increases in drug approvals. Before the Orphan Drug Act went into effect (between 1979 and 1984), mortality from rare diseases grew at the same rate as mortality from other diseases. In contrast, during the next five years, mortality from rare diseases grew more slowly than mortality from other diseases. I estimate that one additional orphan drug approval in year t prevents 211 deaths in year t+1 and ultimately prevents 499 deaths, and that about 108 thousand deaths from rare diseases will ultimately be prevented by all of the 216 orphan drugs tha t have been approved since 1983. Deaths are more closely related to the number of orphan product designations (which include experimental drugs) than they are to the number of approvals. Consistent with previous patient- level studies of HIV, I find that new drugs played a key role in the post-1995 decline in HIV mortality. I estimate that one additional HIV drug approval in year t prevents 5986 HIV deaths in year t+1 and ultimately prevents 33,819 HIV deaths. HIV drug approvals have reduced mortality both directly and indirectly (via increased drug consumption). HIV mortality depends on both the quality and the quantity of medications consumed, and new drug approvals have a sizeable impact on drug consumption: one additional HIV drug approval in year t results in 1.2 million additional HIV drug units consumed in year t+1 and ultimately result in 3.6 million additional HIV drug units.

Bloom, David E.  David Canning and Jaypee Sevilla.  "Economic Growth and the Demographic Transition."  #8685. December 2001.  87 pages.
Abstract:  For decades, economists and social thinkers have debated the influence of population change on economic growth. Three alternative positions define this debate: that population growth restricts, promotes, or is independent of economic growth. Proponents of each explanation can find evidence to support their cases. All of these explanations, however, focus on population size and growth. In recent years, however, the debate has under-emphasized a critical issue, the age structure of the population (that is, the way in which the population is distributed across different age groups), which can change dramatically as the population grows. Because people's economic behavior varies at different stages of life, changes in a country's age structure can have significant effects on its economic performance. Nations with a high proportion of children are likely to devote a high proportion of resources to their care, which tends to depress the pace of economic growth. By contrast, if most of a nation's population falls within the working ages, the added productivity of this group can produce a 'demographic dividend' of economic growth, assuming that policies to take advantage of this are in place. In fact, the combined effect of this large working-age population and health, family, labor, financial, and human capital policies can create virtuous cycles of wealth creation. And if a large proportion of a nation's population consists of the elderly, the effects can be similar to those of a very young population. A large share of resources is needed by a relatively less productive segment of the population, which likewise can inhibit economic growth. After tracing the history of theories of the effects of population growth, this report reviews evidence on the relevance of changes in age structure for economic growth. It also examines the relationship between population change and economic development in particular regions of the world: East Asia; Japan; OECD, North America and Western Europe; South-central and Southeast Asia; Latin America; Middle East and North Africa; Sub-Saharan Africa; and Eastern Europe and the former Soviet Union. Finally, it discusses the key policy variables that, combined with reduced fertility and increases in the working-age population, have contributed to economic growth in some areas of the developing world.

Bongaarts, John.  "The end of the fertility transition in the developed world."   No. 152.  36 pages.
Abstract:  By the late 1990s fertility in the developed world had declined to 1.6 births per woman, a level substantially lower than projected in the 1980s.  This study examines recent trends and patterns in fertility in the developed world with particular emphasis on the effects and implications of changes in the timing of childbearing.  The main objective is to demonstrate that while fertility in these countries is indeed low, women's childbearing levels are not as low as period measures such as the total fertility rate suggest.  To obtain a full understanding of the various dimensions of fertility change, several indicators are examined, including period and cohort fertility by birth order and childbearing preferences.  An analysis of these indicators demonstrates that period fertility measures in many developed countries are temporarily depressed by a rise in the mean age at childbearing.  The distortion of the TFR is as great as 0.4 birth per woman in Italy and Spain.  These effects have been present in many developed countries since the 1970s and could continue for years into the future.  But tempo effects are temporary in nature and once the postponement of childbearing ends—as it eventually must—the corresponding fertility-depressing effect stops, thus putting upward pressure on period fertility.  Countries with very low fertility and substantial tempo effects may well experience modest rises in fertility in the near future if the timing of childbearing stabilizes.  Even if this happens, however, it seems highly unlikely that fertility will rebound to the replacement level.

Mensch, Barbara S., Paul C. Hewett, and Annabel Erulkar.  "The reporting of sensitive behavior among adolescents: A methodological experiment in Kenya."  No. 151.  38 pages.
Abstract:  This paper assesses whether audio computer-assisted self-interviewing (audio-CASI), a technique designed in the United States to collect data on sensitive behaviors, is a feasible method of survey data collection in a developing-country setting and whether it produces more valid reporting of sexual activity and related behaviors than traditional survey methods.  The analysis is based on interviews with nearly 4,400 unmarried adolescents aged 15-21 in Nyeri, a rural district of Kenya that was selected because previous research had indicated a wide discrepancy in the reporting of premarital sexual behavior between boys and girls.  The study was based on a quasi-experimental design in which respondents were randomly allocated to one of three interviewing modes—faced-to-face interviews, paper and pencil self-administered interviews, and audio-CASI—with the presupposition that increased privacy would elicit more reliable responses.  The interview context was found to have a substantial effect on responses to sensitive questions about sexual and other risky behaviors among young people.  Results indicate substantial and significant differences in reported rates of premarital sex across interview modes.  For boys, who we suspect exaggerate sexual experience in face-to-face interviews, the effect is in the expected direction, with a 23 percent drop in reported sexual activity in the audio-CASI mode.  For girls, who we speculate underreport sexual activity when interviewed face-to-face, there is also a large difference by mode, but the effect is not in the hypothesized direction, with respondents reporting twice as much sexual activity in the interviewer mode as in the audio-CASI mode.  While the audio-CASI technology performed well, with minimal mechanical problems, and while respondents were able to complete the survey with limited training, some members of the community reacted adversely to the survey, especially to the use of the computer.  We consider whether this may have had an effect on the response patterns of adolescents.

Lloyd, Cynthia B., Sahar El Tawila, Wesley H. Clark, and Barbara S. Mensch..  "Determinants of educational attainment among adolescents in Egypt: Does school quality make a difference?"  No. 150.  39 pages.
Abstract:  The paper explores empirically the relationship between school quality in Egyptian preparatory (middle) schools and the likelihood of school dropout either during preparatory school or before the completion of secondary school.  Despite strong empirical evidence for the many positive social and economic returns associated with more years of schooling, there has been little research exploring how the quality of particular schools might influence grade levels attained.  The authors address this research gap using detailed data on Egyptian preparatory schools (grades 6—8, the last three years of the eight years of basic schooling) that are linked with a national survey of Egyptian adolescents.  The results confirm that school quality is associated with grade levels attained.  For both boys and girls, the elements of school quality that matter include traditional elements such as time available for learning and material resources, including teacher quality, as well as some aspects of school and classroom dynamics, in particular treatment by teachers and teacher attitudes.  A comparison of these results with a similarly designed study in Kenya by some of the same authors suggests that the specific features of school quality that matter for educational outcomes are context specific and differ between boys and girls.  Gender roles in society, as well as school quality and teacher attitudes about the academic capabilities of adolescent boys and girls, shape the ways in which schools influence boys and girls in a particular setting.  At the same time as schools empower young people with knowledge and skills, they also reflect and reinforce societal norms, including norms about gender roles.

De Vos, Susan, Patricio Solís, and Verónica Montes de Oca. "Receipt of Instrumental Assistance and Extended Family Residence Among Elders in Mexico."  2001-18.  October 200.  48 pages.
Abstract:  This paper focuses on informal instrumental help received by a nationally-representative sample of elderly Mexican men age 60 and over gathered in 1994. About half the men received in-kind or domestic assistance in the last month, while about two-fifths received financial assistance, and a little more than a quarter received physical assistance. These figures must be interpreted alongside the facts that almost half of the men were still working, over half (57%) had no discernable health limitation and roughly a quarter were still living in simple family households with one or more unmarried children.

The common assumption that living arrangements helps indicate assistance seems valid. When receipt of help was regressed on living arrangements and a number of other socioeconomic characteristics, living arrangements stayed an important predictor. Other factors stayed important too however. This suggests that help is a multidimensional concept that includes, but is not limited to coresidence. Coresidence is neither a sufficient nor even a necessary condition.

In fact, many elders who received help, received some of that help from non-coresiding relatives. Remittances were important, but we found that help from non-coresiding relatives or friends included in-kind, domestic and physical assistance as well as financial assistance.  Perhaps it is time to dust off notions of a modified extended family, and in turn modify them, to help us understand the situation in Mexico. Questions about geographic distance, in addition to coresidence, could be helpful.

Marks, Nadine F., James David Lambert, and Hey Jung Jun.  "The Effects of Transitions in Filial Caregiving on Mental and Physical Health: A Prospective U.S. National Study."  2001-16.  November 2001.  40 pages.
Abstract:  
Purpose: This study examined the effects of transitioning into the role of filial caregiver, continuation in filial caregiver role over a period of at least five years, and exiting the role of filial caregiving due to parental death on mental and physical health. Further, it evaluated the moderation of caregiving effects by gender, relationship quality, filial obligation, race-ethnicity, education, income, employment status, marital status, and parental status.

Design and Methods: Data from adults aged 25-65 in 1987-88 and followed up longitudinally in 1992-94 (National Survey of Families and Households) was analyzed (N=1,476). Outcomes included depression, hostility, global happiness, self-esteem, personal mastery, psychological wellness, and self-assessed global health. Multivariate regression models were estimated.

Results: Results suggested that the transition to filial caregiving at a relatively high level of involvement was associated with more depression for men. Continuous care was associated with more hostility, a greater decline in happiness, and a greater decline in self-assessed global health among men. Adult children ending parent care due to death reported mental and physical health similar to noncaregiving adult children. Gender differences suggested men may experience more of mental and physical health risk due to caregiving than women. Relationship quality, filial obligation, social status characteristics, and other role commitments influence the effects of entering into filial caregiving, often in different ways for men and women.

Discussion: Filial care in the U.S. population is not consistently associated with compromised mental and physical health. Gender, relationship quality, filial attitudes, and multiple social context factors moderate the effects of entering into filial care and should be examined further in future research.
